Rain-shielding shed intelligent ventilation device and control method thereof

Abstract

The invention discloses a rain-shielding shed intelligent ventilation device and a control method thereof. The rain-shielding shed intelligent ventilation device comprises a ventilation opening formedin a shed cloth and a heat dissipating device mounted on a vertical column in a ventilation opening covering area. The heat dissipating device comprises a controller, an electric pushing rod and a connecting block fixedly mounted in an inner cavity of the vertical column; a pushing rod body of the electric pushing rod is fixed into a sleeve, and the end, away from the pushing rod body, of the electric pushing rod is fixed to the connecting block; the inner diameter of the sleeve is greater than the outer diameter of the vertical column or the outer diameter of the sleeve is less than the inner diameter of the vertical column, and when the electric pushing rod moves to the maximum stroke, the lower end of the sleeve is located in the vertical column or the upper end of the vertical columnis located in the sleeve; a supporting frame is fixedly mounted at the upper end of the sleeve, and connected with a sealing shed cloth with the size being greater than the size of the ventilation opening; the electric pushing rod is connected with a controller, and the controller and the electric pushing rod are both connected with a power supply module; and the controller of the heat dissipatingdevice is electrically connected with a temperature sensor in a heat dissipating area covered by the heat dissipating device during heat dissipating.

Description

technical field [0001] The invention relates to a ventilator, in particular to an intelligent ventilator for a rain shelter and a control method thereof. Background technique [0002] Agricultural greenhouses have been widely used in agricultural production activities such as vegetable planting, flower cultivation and seed breeding all over the world. The basic structure is composed of steel frame main body and thermal insulation plastic film. The greenhouse can play the role of thermal insulation in winter. , but in spring and autumn, the temperature difference between day and night is large. When there is sufficient sunlight, the temperature in the greenhouse is very high, while the ground temperature in the greenhouse at night is very low. The root system of fruits and vegetables does not have a good growth environment, which restricts the growth of fruits and vegetables. Since the heat inside the greenhouse cannot be reasonably adjusted and distributed, it not only incre...

[0002] Agricultural greenhouses have been widely used in agricultural production activities such as vegetable planting, flower cultivation and seed breeding all over the world. The basic structure is composed of steel frame main body and thermal insulation plastic film. The greenhouse can play the role of thermal insulation in winter. , but in spring and autumn, the temperature difference between day and night is large. When the sun is sufficient, the temperature in the greenhouse is very high, while the ground temperature in the greenhouse at night is very low. The roots of fruits and vegetables do not have a good growth environment, which restricts the growth of fruits and vegetables.

Since the heat inside the greenhouse cannot be adjusted and distributed reasonably, it not only increases the cost, but also makes the yield and quality of the crops unable to be guaranteed.
